Tiamat, the Scaled Tyrant is the evil queen of dragons. She is a fearsome goddess of greed, envy, and hoarded wealth, and the patron of most chromatic dragons. She is the sworn enemy of Bahamut.[6]


Depiction of Tiamat's divine aspect from Fizban's Treasury of Dragons, p. 166.[art 3]

Tiamat is depicted as a massive, five-headed dragon, with each head a different color of chromatic dragon, and her leathery wings spread poisonous clouds.[2]

Commandments of the Scaled Tyrant

Commandments of the Scaled Tyrant

  • Amass wealth, but spend little. The gold—and the power that comes with it—is sufficient reward in itself.

  • Do not forgive nor forget an indignity to yourself. Let no affront go unpunished.

  • Take what you covet. Those without the strength to defend their dominion are not worthy of it.


Since the Founding, Tiamat manifested deep hatred for the Platinum Dragon, disturbing her cults network.[7]


During the Founding, the Scaled Tyrant and the Platinum Dragon created the dragons of Tal'Dorei to protect their interests on the Material Plane.[8]

During the Age of Arcanum, Tiamat created one of the Arms of the Betrayers, given to her chosen champion of Ghor Dranas: the Will of the Talon, a war pick with the life force of a bone devil.[9] One of the Vestiges of Divergence is also associated with Tiamat: the Wreath of the Prism.[10]

According to the particularly pervasive tale, the Scaled Tyrant and the Platinum Dragon created the dragonborn during the Calamity, their loyal soldiers who eventually earned their freedom.[11]

Tiamat is imprisoned in Avernus, the first layer of the Nine Hells.[2]

CelebriD&D with Joe Manganiello

Tiamat sent visions of a locked-away loop of golden thorns and gems to her follower Arkhan in his dreams. He sought out this artifact and, with the help of a group of mercenaries, eventually acquired the Wreath of the Prism from the Vault of Shumas in the Aggrad Mountains of Marquet.

Following the Chroma Crisis

For centuries, paladins of Bahamut had kept the worship of Tiamat limited to chromatic dragons, but after the Chroma Conclave emerged and attacked Emon, secretive humanoid cults sprang up. Some of the oligarchs of Tal'Dorei also covertly turned to Tiamat as their accumulated wealth was depleted.[7]

"Stalker in the Swamp" (2x21)

In 835 PD, Calianna Mordsson, a sorcerer of draconic origins who escaped the Cult of the Caustic Heart, sought the help of the Mighty Nein to find and destroy an artifact that would allow ritualistic communication with Tiamat before the cult could acquire it. The adventurers did find the bowl in the possession of several merrow, and Yasha was able to destroy the magic item with Magician's Judge.


Sapped by the exorbitant cost of rebuilding the destruction of the Chroma Conclave, a number of oligarchs in Tal'Dorei have turned to the Scaled Tyrant in secret to replenish their hoarded wealth.[7]
